Do you work with existing React codebases?

Yes. Most engagements start with a codebase somebody else wrote. We read it, map the parts that are load-bearing, and change them incrementally rather than proposing a rewrite you did not ask for.

React or Next.js — which should we use?

If the pages need to be found in search, indexed by AI answer engines, or shared as links, use Next.js: server rendering gives crawlers complete HTML. If the product sits behind a login and search visibility is irrelevant, plain React is often the simpler choice.

Can you build a design system for several teams?

Yes. That is exactly what Puzzle was at TransPerfect — a Storybook library shared team-wide, with a custom state-management layer alongside it.

React & Next.js Development

React frontends that stay fast as the product grows.

We build and rebuild React frontends for products that have outgrown their first version. That means Next.js applications rendered on the server, component libraries a whole team can share, and interfaces that hold up under real traffic instead of only on a designer's machine.

What this includes

Next.js App Router applications

Server components, streaming, and route-level caching, set up so the HTML a crawler receives is the same HTML a visitor sees. Server rendering is a search requirement, not a performance nicety.

Design systems and component libraries

Shared component libraries documented in Storybook, versioned and consumed by several product teams — the same pattern we built and maintained as Puzzle at TransPerfect.

Accessible interfaces

Keyboard paths, focus management, form errors wired to the fields they describe, and colour contrast measured rather than assumed. Accessibility is treated as load-bearing, not as a retrofit.

Migration and modernisation

Class components to hooks, Create React App to Next.js, JavaScript to strict TypeScript — done incrementally, with the product shipping the whole time.

React work here includes an enterprise translation-memory platform at TransPerfect, a Storybook component library used across product teams, and a DNA research interface built on React and Redux.
